a week or two ago i posted i was havin some problems with my truck idling down and stalling out. I took the advice and cleaned the throttle body and IAC they both had alot of carbon build up. The truck is idling better but still will idle down really low but its not stallin out now. Any other ideas? Could the IAC need replacin or should i look elsewhere rite now

 

good to hear. what about your plugs?

 

the plugs arent very old they might have 10-15k on them.

 

i may have asked this last time but have you checked your tps?

 

how do check it?

 

you need to buy a voltmeter and backprobe the wires. and make sure theres a smoothe curve from idle to wot.

 

I ll have to try that but if it was the tps wouldnt it do it ever time it idles down? Mine only does it randomly.
Oh is my pic showing up on my post?

 

no pic....yea i honestly dont know that much but doing the things i mentioned will eliminate some. and plus cleaning your tb and iac is just preventative maint.

This is from 95_318SLT, when he helped me with what i thought was a tps prob.

"So the frontmost (closest to grill) terminal is 5 volts in. The middle terminal is signal to PCM. The rearmost terminal is ground. So if you put the multimeter in the front and rear terminals, you should get a constant 5 volts. If you put it in the middle and rear terminals, you should get a varying voltage depending on throttle position. If you do not get a varying signal, the TPS is bad."
